## Vordefinierte Konstanten

`FilesystemIterator::CURRENT_AS_PATHNAME`

  Makes FilesystemIterator::current() return the pathname.

`FilesystemIterator::CURRENT_AS_FILEINFO`

  Makes FilesystemIterator::current() return an SplFileInfo instance.

`FilesystemIterator::CURRENT_AS_SELF`

  Makes FilesystemIterator::current() return $this (the FilesystemIterator).

`FilesystemIterator::CURRENT_MODE_MASK`

  Masks FilesystemIterator::current()

`FilesystemIterator::KEY_AS_PATHNAME`

  Makes FilesystemIterator::key() return the pathname.

`FilesystemIterator::KEY_AS_FILENAME`

  Makes FilesystemIterator::key() return the filename.

`FilesystemIterator::FOLLOW_SYMLINKS`

  Makes RecursiveDirectoryIterator::hasChildren() follow symlinks.

`FilesystemIterator::KEY_MODE_MASK`

  Masks FilesystemIterator::key()

`FilesystemIterator::NEW_CURRENT_AND_KEY`

  Same as `FilesystemIterator::KEY_AS_FILENAME | FilesystemIterator::CURRENT_AS_FILEINFO`.

`FilesystemIterator::OTHER_MODE_MASK`

  Mask used for FilesystemIterator::getFlags() and FilesystemIterator::setFlags().

`FilesystemIterator::SKIP_DOTS`

  Skips dot files (`.` and `..`).

`FilesystemIterator::UNIX_PATHS`

  Makes paths use Unix-style forward slash irrespective of system default. Note that the `path` that is passed to the constructor is not modified.
